(Industrial Application Field) This invention relates to a method for dyeing a fiber structure made of recycled cellulose fibers and wool. (Prior art) When dyeing a fiber structure made of recycled cellulose fibers and wool with a reactive dye, if dyed with a pH in the acidic range that protects wool, for example PH6, the wool will be dyed, but the recycled cellulose fibers will be dyed. There is a drawback that it cannot be dyed. Regenerated cellulose fibers are usually dyed with alkaline reactive dyes, but when the fiber structure is dyed using a normal dyeing method, it is difficult to dye the wool, which also has the disadvantage that it cannot be dyed to the same color. In particular, when dyeing deep colors such as black, dark blue, and dark red, simultaneous dyeing in one bath with reactive dyes is difficult.
For dyeing these fiber structures made of recycled cellulose fibers and wool, a one-bath two-stage method or a two-bath dyeing method is required. (Problems to be Solved by the Invention) When dyeing a fiber structure made of recycled cellulose fibers and wool, the one-bath two-stage and two-bath dyeing methods are complicated in operation and result in an increase in dyeing costs. . On the other hand, the one-bath simultaneous dyeing method brings about a reduction in dyeing costs, but has the disadvantage that dyeing does not occur when dyeing deep colors such as black, dark blue, and dark red. An object of the present invention is to provide a method for simultaneous dyeing of the fiber structure in one bath. (Means for Solving the Problems) The method of the present invention involves pre-treating with an alkaline aqueous solution having a pH of 9 to 11, preferably PH 9 to 10, when dyeing a fiber structure made of recycled cellulose fibers and wool.
The solubility of the fiber structure in an N/10 NaOH aqueous solution is 1 to 4%, preferably 1 to 2%, and the Beilereck method water absorption is 10 to 13 cm, preferably 11 to 12 cm.
It is characterized by being dyed after being made into cm. The recycled cellulose fibers applicable to the present invention may be either viscose rayon or cuprammonium rayon. Examples of fiber structures made of recycled cellulose fibers and wool include blended yarns of these and woven or knitted fabrics thereof, intertwisted yarns of yarns made of recycled cellulose fibers and wool yarn, interwoven fabrics, interwoven knitted fabrics, etc. . The mixing ratio of recycled cellulose fiber and wool is
Usually 50-97% recycled cellulose fiber and 50-3% wool, preferably 70-95% recycled cellulose fiber and 30% wool.
~5%. Furthermore, in the present invention, examples of the alkaline aqueous solution used include aqueous solutions of sodium hydroxide, sodium carbonate, sodium phosphate, or ammonia, which may be used alone or in combination. It can also be used in combination with hydrogen peroxide. The pH of the alkaline aqueous solution is 9-11, preferably 9-10.
The temperature is usually 60-95℃, preferably 60-95℃.
Process in warm water at 80℃ for 30-60 minutes. The concentration of coexisting hydrogen peroxide is 0 to 50g/preferably 10g/
The following is good. As a processing method, a cold batch method may be used. The pretreated fiber structure is colored by dyeing, and reactive dyes for cellulose, direct dyes, and threne dyes can be used, and the methods include exhaustion method, patination method, cold batch method, etc. is possible, and the commonly used cellulose fiber dyeing method can be used as is. Generally, when wool is pretreated with an alkaline aqueous solution with a pH of less than 8 to 9, it becomes less brittle, but when dyed in this pH range, it does not show color constancy. When pre-treated and dyed with an alkaline aqueous solution with a pH higher than 11, the wool shows the same color, but the wool becomes brittle.
The texture is noticeably hardened. It goes without saying that the texture of the pretreated fiber structure changes depending on the combination of pH and temperature of the alkaline aqueous solution during pretreatment, but the
10NaOH solubility is 1-4%, preferably 1-2
% and Virex method water absorption of 10 to 13 cm, preferably 11 to 12 cm, which is the range in which the same color property and hand feel are good. (Effect of the invention) The present invention is a dyeing method that is commonly used not only for light colors and medium colors but also for dark colors such as black, dark blue, and dark red, which had the disadvantage of not being dyed in the same color. It can be dyed, has less brittleness, and has a good texture. Such effects can be obtained by treatment with an alkaline aqueous solution under specific conditions, with a solubility in N/10 NaOH aqueous solution of 1-4%, preferably 1-2% and a Byreck method water absorption of 10-13 cm, preferably 11-12 cm.
It can only be obtained by coloring a fibrous structure that has been made into a fibrous material, and has great industrial utility value. (Example) The present invention will be specifically described below with reference to Examples. In addition, strength, whiteness, alkali solubility, water absorption, dyeability, and texture described in Examples were measured by the following methods. (1) Tenacity (g) Warp and weft yarns were taken out from the fabric and the yarn tenacity was measured using a Tensilon. (2) Whiteness (%) Using a spectrophotometer attached to a reflection light measuring device using an integrating sphere, the reflectance (%) for magnesium oxide was measured at a wavelength of 400 mm and used as an index of whiteness. (3) Alkali solubility (%) Using 100 times the amount of N/10NaOH solution, treatment was performed at 65°C for 1 hour, and the weight loss rate before and after treatment was defined as solubility. (4) Water absorption (cm) The water absorption performance was defined as the measured value of JISL1096 water absorption rate (Bayreck method). (5) Dyeability The presence or absence of a frosty tone on the dyed fabric was visually determined. (6) Texture The texture of the starched fabric was set as 5, and was expressed as an average value with 4 being slightly hard, 3 being slightly hard, 2 being quite hard, and 1 being very hard. (Example 1) In the drawing process, after blending so that the blend ratio is rayon 80 and wool 20, it is spun to make 30S, which is used as the weft, rayon 30S is used as the warp, the density is 100, and the weft is 30S.

Dyeing was carried out at 60° C. for 60 minutes using 20 g of sodium carbonate at a bath ratio of 1:30 to obtain a good black dyed product. Comparative Example 1 is one without pre-treatment (sizing cloth),
In Comparative Example 2, the pH of the aqueous solution during pretreatment was set to 12.0, and the other conditions were exactly the same as in Inventive Example 1. The results are shown in Table 1.

結果を第５表に示す。[Table] Comparative Example 1 had an unsatisfactory frosty appearance. In Comparative Example 2, although the frosting was improved, the strength was significantly lowered and the texture was also significantly hardened. In Inventive Example 1, the frosted texture was improved, and there was little decrease in strength, and there was little hardening of the texture. (Example 5) The twill fabric of Example 1 was desized using an enzymatic desizing agent, and 10 g of H 2 O 2 (35% product) and Rastavil were added.
K1095 (manufactured by Hoechst, anionic surfactant) 7
After applying a pre-treatment liquid containing 1.5 g / PH10 and winding it into a roll, it was heated at 25℃ for 15 minutes to prevent moisture evaporation.
After leaving it for a while, it was washed with water and dried. Next, dyeing was carried out in the same manner as in Example 4 to obtain a beautiful red dyed product. In Comparative Example 1, no pretreatment was performed (desizing cloth), and in Comparative Example 2, the pH of the pretreatment liquid was 8.0, and the other conditions were exactly the same as in Inventive Example 1. In the comparative example, unsatisfactory results were obtained. The results are shown in Table 5.

In Comparative Example 2, although the frosting was improved, the strength was greatly reduced, the hand was hardened, and the wool became brittle, which is not preferable. Inventive Examples 1 and 2, good black-dyed products with improved frosting tone were obtained, and there was little decrease in strength.
There was also little hardening of the texture.
